Title: Oil-water filtering separator with electrostatic and magnetic water filtration
IPC: C02F1/40
Filed: 1999-06-28
Abstract: 1. An oil-water filtering separator, comprising body with outer and inner shells, a heater in the form of steam- water coil disposed in a gap between the shells, filtering granulated filler in the form of thermally-tempered balls arranged in the internal space of the inner shell in its bottom part, gravity oil settler and a tank for purified water, a branch pipe for feeding cleaning water, a branch pipe removing mud and sludge, branch pipe for removing oil products, a branch pipe for removing purified water, branch pipes for feeding heat carrier and removing condensate, air and safety valves, a heat-sensing device, characterized in that the separator includes an extractor and a recuperator, the body is provided with a cover and a bottom, where arranged correspondingly gravity oil settler and a collector of purified water with tangential branch pipes for feeding cleaning water connected with the outer shell moving tangentially to the circumference, branch pipes for feeding washing water and blowoff air, the cover is provided with a branch pipe for removing oil products, an air valve, wherein the extractor designed in the form of electrically-insulated cylindrical cassette, the inner space of which granulated thermally-stressed coarse filler retained from washing out by a disk perforated with longitudinal slots and arranged atop and from the bottom is retained by at least one filter of disk and edge type, a recuperator consisting of at least one electrically-insulated conic edge filter, which is under the positive potential, and toroidal magnets (constant or electric), creating magnetic field, the field vector of which is directed opposing velocity vector of the laminar stream of cleaning water, and in the bottom part of the internal space of the inner shell a granulated thermally-stressed small-sized filler is arranged, wherein at least on 1, 5?3 lower turns of the steam-water coil of the heater horizontal ribs are provided in one plane, at the end of the vertical pipe of purified water removal, arranged in the collector of purified water, a cone is provided, and in the bottom part of the internal space of the inner shell a filter of a cap and edge type is provided, radial ribs of constant heat resistance are arranged along the whole height of the inner shell from the recuperator to the filter of cap and edge type. 2. The separator as claimed in claim 1, characterized in that the filter of disk-edge type is designed in the form of perforated disks with holes displaced relative to each other to a space equal 4/5?5/6 of the filler ball diameter, the displacement is provided by distance washers enabling to close the holes. 3. The separator as claimed in claims 1 to 2, characterized in that the filter of cone and edge type is designed in the form of a perforated disk with holes, above each a cone is fastened with slots and stiffening ribs. 4. The separator as claimed in claims 1 to 3, characterized in that the filter of cap and edge type is designed in the form of a perforated disk with holes, above each a cap is fastened with slots on the cylindrical part and partially on the bottom. 5. The separator as claimed in claims 1 to 4, characterized in that the balls of the filtering filler are made of metal, glass or ceramics.
